@hamburger,
It's a little complicated...
What is currently on your profile page USED to be the "My Posts" view.
That was changed so that you get a view of all of the THREADS you have made a post in, and you can sort them in various ways.
So whatever THREAD you posted the Afghanistan comment in should show. You click on that to go to the thread and see what people have said after you, if anything.
Separately, the profile page lists just your actual posts, most recent first. (That's new -- it appeared sometime today.)
Hope that helps and doesn't just confuse things further...
